Le Corbeau (The Raven) is a 1943 French film directed by Henri-Georges Clouzot. The film was notable for causing serious trouble to its director after World War II because it had been produced by Continental Films, a German production company established in France in the early months of the war, and because the film had been perceived by the underground and the Communist press as vilifying the French people. Because of this, Clouzot was initially banned for life from directing in France and the film too was banned, but both bans were lifted in 1947. The film was remade as The 13th Letter (1951) by Otto Preminger.
The word corbeau has always been the French for raven or crow, but has now acquired the sense of a sender of anonymous letters. One of the most infamous cases of this kind centred on the murder of four-year-old Grégoire Villemin. A sender of anonymous letters claimed responsibility and at one stage the boy's own mother was accused of sending the letters.
